so I guess you are saying that whether the downward force measured by a scale on the ground would register a bigger reading if you jump onto the scale as oppose to standing still on it? what do you think?

Force is equal to mass times acceleration. The same velocity can be achieved with a faster acceleration over a shorter period of time. There's no limit to the amount of force involved in a 2 foot landing, other than the maximum deceleration will be limited by how much compression there is at the contact point.

the force you are talking about is probably the instantaneous reading NOT at impact but when your body has just been fully decelerate to velocity zero I think, and before the scale re-adjust and show your "true weight"

mind you there are all those usual stuff like air resistance, or how you may destroy the scale etc...ie. what is the displacement during deceleration (otherwise it is probably not just 2 feet the total distance travelled) or whether deceleration is constant during that time....
